Throughout this disclosure, the term outer cover refers to a portion of an article (also referred to as a backsheet) that forms the outer surface of the wearable absorbent article and extends beyond the edges of the absorbent core. , Generally covering a significant portion of the wearer's buttocks, generally resembling the appearance of underwear. As described herein, the outer cover can be constructed in various ways. In various embodiments, the outer cover can coincide with and / or define the chassis of the wearable absorbent article.

  Some absorbent articles are disposable. The disposable absorbent article is configured to be discarded after a single use (eg, not intended to be reused, stored, or washed). Examples of disposable absorbent articles include disposable diapers, disposable training pants, disposable incontinence underwear, and feminine care pads and liners.

  Some absorbent articles are reusable. As used herein, the term “reusable” means that the referenced material, component, or whole of the absorbent article is regenerated and / or used once (eg, changing diapers). It means being configured to be reused beyond. For some reusable absorbent articles, some or some or substantially all or all of the article is washable or wash-resistant as defined and described herein. Can have. As an example, a wearable absorbent article can include an outer cover that is washable or wash-resistant. In other reusable absorbent articles, some or some or substantially all or all of the article may not be washable or not wash resistant. For example, by using a material such as a nonwoven fabric used for disposable articles such as diapers, the absorbent article can be configured as a reusable absorbent article.

  In various embodiments, the reusable outer cover can be configured to perform various functions that provide various benefits to the wearer of the article and / or the wearer's caregiver. In various embodiments, the reusable outer cover can be configured to provide liquid impermeability that can help contain waste by the absorbent article. In various embodiments, the reusable outer cover can be configured to provide vapor permeability (eg, breathability) that can help maintain a wearer's healthy skin. In various embodiments, the reusable outer cover can be elastically stretchable, inelastically stretchable, and / or non-stretchable in one or more specific directions. Can be configured. In various embodiments, at least a portion of the reusable outer cover, such as a portion of the inner layer, may be absorbent to control minor leak events from the absorbent core.

  Specifically, some or some or substantially all or all of the reusable outer cover may be worn while the article is being worn by the wearer while the article is being applied to the wearer. And can be configured to stretch and relax to a certain degree while the article contains waste. The reusable outer cover can be configured to easily stretch while the article is being applied to the wearer to help facilitate application.

As an example, a reusable wearable absorbent article can include a wash-resistant outer cover. Laundry resistant articles generally experience degradation after less wash cycles than washable articles. For example, the wash-resistant material may experience a significant degradation in appearance or performance after 5 or 10 wash cycles.

Exemplary Washable Outer Cover The following is a description of an exemplary washable outer cover for use in a pre-fastened wearable absorbent article. Typical washable outer covers are outer layer, inner layer, left and right leg bands, front waist band and rear waist band, fixation band, landing zone, side ear fastener, side ear core, and absorbent. Sex core fastening elements.

  Throughout this disclosure, the term “front side” refers to the side of the material that will be the outer surface of the finished product, and the term “back side” refers to the inner surface of the finished product (or the layers and layers of the finished product in embodiments having multiple layers). Refers to the side of the material that will be between. When completed, the front side of the outer layer is the side facing the garment and the front side of the inner layer is the side facing the wearer.

  Each element of a representative washable outer cover is formed of one or more specific materials. The outer layer material is a soft stretchable knit made of modal or lycra. For example, the outer layer material can be 95% modal and 5% lycra. The inner layer material is made of two materials. The inner layer material configured to be placed on the back of the article is configured to be stretchable in the lateral direction to provide a comfortable fit. The back inner layer material is a soft stretchable knitted fabric made of polyester with spandex. For example, the inner layer material can be 94% polyester and 6% spandex. The inner layer material disposed on the crotch and front of the article is configured to be hydrophobic to resist urine entry. For example, the inner layer material can be 90% nylon tricot and 10% spandex.

  The leg and waist bands are formed of an elastic inner material and a soft extensible fabric outer material. For example, the inner elastic band material can be a natural stretch material of about 10 mm width. The inner elastic band material is similar to the back inner layer material. The outer fabric band material is similar to the outer layer material.

  The fixation band material is a stretchable knitted fabric piece made of polyester with spandex. For example, the stretchable knitted fabric can be 90 mm polyester and 10% spandex and 25 mm wide. The fixed band material is configured to have a higher modulus and lower elastic hysteresis than the outer layer material. The landing zone and side ear fasteners each comprise a mechanical hook and loop fastening system with a corresponding stitchable loop and hook patch. The ear core material is a woven fusible core that helps the ear to resist bending or buckling. The absorbent core fastening element is also a loop patch configured to fasten with a hook on the absorbent core.

  To make a representative washable outer cover, each material is first cut into the desired shape. The outer layer material and the inner layer material are cut into the same shape, which is the oval shape of the outer cover.

  For leg bands, the two pieces of inner elastic band material are cut to lengths for the retractable leg cuff portions on the left or right longitudinal side of the outer cover, respectively. For example, the length of the inner elastic leg band can be about 220 mm. Also, each of the two pieces of outer fabric band material is of a specific length and width such that each piece of outer fabric leg band material can be folded in half vertically to wrap one piece of inner elastic leg band material. Disconnect.

  Similarly, for the waistband, the two pieces of inner elastic band material are cut to lengths for the retractable waist edge portion of the front or rear end of the outer cover, respectively. For example, the length of the inner elastic waistband can be about 245 mm. Further, the two pieces of outer fabric band material are each of a specific length and width such that each piece of outer fabric waist band material can be folded in half vertically to wrap one piece of inner elastic waist band material. Disconnect.

  One fixation band is cut to an appropriate length from one rear ear to the other rear ear. Cut the two side ear fasteners to fit the side ears behind the outer cover. One landing zone is cut to fit in front of the outer cover, allowing side ear fasteners. The eight side ear cores are cut to fit the inner surfaces of the side ears on the front and rear sides of the outer cover. The two absorbent core fastening elements are cut to allow hooks on the absorbent core.

  Second, the cut material is assembled together. The landing zone is sewn to the front side of the front part of the outer cover. The four side ear cores are fused to the back side of the outer layer, one on each of the left and right ears at the front and rear.

  The leg bands are sewn to the retractable leg cuffs on the left and right longitudinal sides of the outer cover on the back side of the inner layer and the back side of the outer layer. During this stitching process, the central portion of each leg band is pre-stretched while the inner and outer layers are substantially relaxed. For each leg band, both ends of the inner elastic leg band material are fixed, while the central portion is free to move on the inner surface of the outer fabric leg band material.

  Similarly, the waistband is sewn to the back side of the inner layer and the back side of the outer layer at the retractable waist edge on the front and rear ends of the outer cover. During this stitching process, the central portion of each leg band is pre-stretched while the inner and outer layers are substantially relaxed. For each waistband, both ends of the inner elastic waistband material are fixed, but the central portion is free to move on the inner surface of the outer fabric waistband material.

  The fixing band is sewn to the back side of the inner layer at the rear ear portion and the front ear portion. During this stitching process, both the fixation band and the inner layer are substantially relaxed, i.e., when they are both laid down, neither element has been pre-stretched against the other. The central part of the fixing band cannot be sewn to the inner layer. The side ear fastening portion is sewn to the front side of the inner layer at the left rear ear and the right rear ear. Absorbent core fastening elements are sewn to the front side and back side of the inner layer. The four side ear cores are fused to the back side of the inner layer, one on each of the left and right ears at the front and rear. Next, the inner layer and the outer layer are stitched together and inverted so that the front side is outside. This is the completion of a typical washable outer cover. In the finished outer cover, the central part of the fixation band is free to move with respect to the inner and outer layers. Further, in the completed outer cover, the fixing band is not stretched in advance with respect to the inner layer and the outer layer.

  This representative washable outer cover is intended as a non-limiting example and can be varied in many ways as described below. Any element of the outer cover can comprise one or more secondary components, i.e., one element can be formed of one or more pieces or types of materials. Either or both layers of the outer cover may comprise a single layer of material, and may comprise two or more layers and / or two or more materials. The inner layer may be stretchable both in the horizontal direction and in the vertical direction. The inner layer may be treated to increase hydrophobicity. The inner layer may have various stretchability, hydrophobicity, and / or breathability over its area.

  The outer cover may have various stretchability, hydrophobicity, and / or breathability over its area. The outer cover may not have a fixation band and may have any number of fixation bands or other fixation system components. As an example, the washable outer cover is as described in a US non-provisional patent application entitled “Reusable Wearable Absorbents with Anchoring Systems” filed on Jan. 14, 2010 under agent number 11225M. Which may be configured to include one or more elements of a secure fixation system, which patent application is incorporated herein by reference. As an additional example, a washable outer cover is described in a US non-provisional patent application entitled “Reusable Wearable Absorbent Articles With Anchoring Systems” filed on January 14, 2010 under agent docket 11565. Which can be configured to include one or more elements of a fixation system, which patent application is incorporated herein by reference.

  The outer cover can be provided with a structure to protect the fastening element during the washing process (eg, a protective flap that covers the hook or an adjacent area of the hook where the fastener can be temporarily applied). The absorbent core can be added to the outer cover and / or the absorbent core, such as a pocket, cuff, strap, loop, hook and loop fastener, or any type of fastener. It can be connected to the outer cover by a kind of mechanism. The outer cover can comprise a macro fastener or any other fastening system known in the art. The leg band and the waist band can be made of a single material, laminate, or the like. The leg band and the waist band may be attached only to the inner layer, or may be attached only to the outer layer.

  As will be appreciated by those skilled in the art, in various alternative embodiments, this exemplary washable outer cover may be added in a number of other ways, with additional and / or alternative materials, structures, configurations, and assembly methods. It can be changed with.

  The washable outer cover material can include diapers, pants, underwear, performance garments, sports garments, or any natural or synthetic material known in the general garment or textile arts. These materials include natural materials such as cotton, wool, bamboo, hemp, silk, rayon, and blends of these materials with synthetic fibers. Typical synthetic materials suitable for use in the washable outer cover include polyester, nylon, lycra, spandex, or other elastomeric, breathable waterproof materials (eg, GORE-TEX® (Maryland) HL Gore & Associates, Inc., Elkton), and Outlast ComforTemp fabric (Outlast Technologies, Boulder, Colorado). For example, US Pat. Nos. 6,514,362 and 6,207,738 And a fabric containing a microencapsulated phase change polymeric material such as COOLMAX® (INVISTA (Wichita, Kans.)). These materials preferably comprise at least one fiber-based material such as a fabric or woven web or non-woven web. However, the outer cover may additionally comprise a film layer to provide enhanced liquid penetration resistance and / or elastic properties to the outer cover. Elastic properties can be added or reinforced by adding other materials to the outer cover, including elastic strands, bands, scrims, and the like. Washable materials include bird's eye fabric, terry, fleece, flannel, knit, stretch knit, sherpa, suede fabric, microfleece, satin, velor, Burley knit, and Polartec (R) Windpro (R) (Polartec, LLC) (Lauren, Mass.)) Can be formed as any known woven or fabric form. Knit textiles are inherently stretchable and elastically superior to woven or non-woven materials, and can provide a better fit, comfort, and / or appearance to the outer cover. Incorporating spandex or other elastomeric fibers can also enhance stretch and elasticity, thereby providing a better fit, comfort, and / or appearance as compared to textiles that do not include such elastic fibers. Can be applied to the outer cover.

  Specific examples of suitable washable outer cover materials include rayon fibers (93%) and spandex (7%) fibers, modal fibers (94%) and spandex (6%) fibers, cotton fibers and spandex fibers, and bamboo. Examples include jersey knit blended with fibers and spandex fibers. A material having a stretch capability of about 30%, or 50%, or 100%, or 150% or more, or 200% or more may be desirable. Examples of suitable materials can have a basis weight of about 0.09 to 0.15 grams / inch 2 per layer or other basis weights.

  The washable outer cover material can be selected to impart the desired comfort, appearance, and performance to the wearable absorbent article. In some cases, it may be desirable to select a washable outer cover material that is sufficiently inexpensive to allow disposal of it when it becomes heavily soiled or damaged, minimizing cost or awareness issues. is there.

  It is contemplated that any washable outer cover disclosed herein can be used with any embodiment of the wearable absorbent article disclosed herein. Exemplary washable outer covers can also be adapted for use with pant-type wearable absorbent articles.

Exemplary Laundry Resistant Outer Cover The following is a description of a representative laundry resistant outer cover for use in a pre-fastened wearable absorbent article. A typical wash resistant outer cover comprises a three layer laminate comprising two stretchable nonwoven materials and an elastically stretchable film sandwiched between the nonwovens. The first stretchable nonwoven forms the garment facing side of the outer cover and the second stretchable nonwoven forms the wearer facing side of the outer cover. The first stretchable nonwoven is a 27 gsm HEC nonwoven (such as the Excell Style 382D model available from Fiberweb / BBA). The elastically stretchable film comprises a 27 gsm Vistamaxx film (resin available from Exxon-Mobil) and has a polyethylene skin layer of about 5 gsm. The second stretchable nonwoven is a 22 gsm nonwoven such as Sofspan 200 available from Fiberweb France.

  The film and the second nonwoven are extruded and bonded to form a two-layer laminate. Two-layer laminates are available as Clopay Corp material M18-2038C. The first nonwoven is bonded to the film side of the two-layer laminate using 0.0006 g / inch 2 of 2031 spiral adhesive (available from Bostik) to form a three-layer laminate. The outer cover also includes a securing band disposed within the three-layer laminate. The securing band is an elastomer film strip having a width of about 25 mm, is located on the back waist of the outer cover and is oriented parallel to the lateral centerline of the outer cover, from the fastener on one side of the outer cover to the opposite side of the outer cover. Extends to the fastener. A three-layer laminate outer cover is then mechanically activated (ie, stretched incrementally laterally) using a ring rolling process. The ring roll tooth pitch of the ring rolling process is 0.25 cm (0.100 ") and the depth of engagement is 0.40 cm (0.158").

  As an example, the wash-resistant cover is as described in a US non-provisional patent application entitled “Reusable Wearable Absorbents with Anchoring Systems” filed on Jan. 14, 2010 under agent number 11225M. This patent application may be configured to include one or more elements of a fixation system, and this patent application is incorporated herein by reference. As an additional example, a wash-resistant cover is described in a US non-provisional patent application entitled “Reusable Wearable Absorbent Articles With Anchoring Systems” filed on Jan. 14, 2010 under agent docket 11565. Which can be configured to include one or more elements of such a fixation system, which patent application is incorporated herein by reference.

  This representative wash-resistant outer cover is intended as a non-limiting example. As will be appreciated by those skilled in the art, in alternative embodiments, this representative wash-resistant outer cover can be varied in a number of ways, along with additional and / or alternative materials, structures, configurations, and assembly methods. Can do.

  Laundry resistant outer covers can be inexpensive enough to allow them to be discarded without cost or awareness even if heavily soiled or damaged. The wash-resistant outer cover material can include any material described herein, including one or more materials contemplated for use in a washable outer cover or a disposable outer cover. When choosing materials to use for the washable outer cover, typically the cheaper and lower quality (eg, lower basis weight, less optimal fiber) version should be used to make the wash resistant The outer cover can be formed. When selecting materials for use in disposable articles (eg, disposable diapers), higher basis weight and / or quality materials may be appropriate. For laundry resistant outer covers, blends or laminates of such materials are also contemplated.

  For example, the design of a disposable wearable absorbent article can be altered to make the article wash-resistant. For example, “Disposable Absorbent Artificial With Substantially Distributed Absorbed Polymer Participant No. 126 published in Dec. 18, 2008, which is incorporated herein by reference.” A wearable absorbent article constructed in can be modified by removing its absorbent core and changing and / or replacing one or more of the remaining components of the article to make the article more robust, Therefore, it can be made wash-resistant.

  Alternatively, or in addition, the various component materials of the wash-resistant outer cover may be less durable but less labor, such as adhesive or mechanical or thermal bonding (eg, instead of stitching) Can be combined using means that require Furthermore, the material build may affect the strength of the material and its ability to withstand degradation when it is subjected to a wash cycle. For example, the type, strength, and degree of bonding of a material can affect the strength of the material, and therefore can also affect whether the material is washable or wash resistant.

  In the case of a wash-resistant outer cover, the material can comprise any natural or synthetic nonwoven web and / or film material known in the diaper or pant art. The wash-resistant material from which the outer cover can be constructed includes polypropylene fibers and / or polyethylene fibers, polyester fibers, and any used to form nonwoven web materials used as components in disposable diapers Other synthetic fibers, as well as blends thereof. Natural fibers such as linen cloth, wool, bamboo, hemp, silk, rayon, etc. may be blended with synthetic fibers to form such a nonwoven web suitable as a component layer for the outer cover. In addition to these materials, films such as polyolefin films (microporous or non-microporous) can also be used for the wash-resistant outer cover.

  Non-limiting examples of fibers, non-woven fabrics, and non-woven fabric and film laminates that may be considered for use as a wash-resistant outer cover material are U.S. Patent Nos. 7,223,818, 7,211,531. No. 7,060,149, No. 6,964,720, No. 6,905,987, No. 6,890,872, No. 6,884,494, No. 6, 878,647, 5,518,801, and U.S. Published Patent Application Nos. 2008/0319407, 2008/0045917, 2007/0293111, 2007/0287983, 2007/0287348. No. 2007/0249254, No. 2007/0203301, No. 2005/0164587.

  The wash-resistant outer cover material may also be selected to give the outer cover the desired comfort, appearance and performance. Also, in some cases, it may be desirable to select a wash-resistant outer cover material that is sufficiently inexpensive to allow disposal in the event of severe soiling or damage with minimal cost or awareness issues. In some cases.

  The outer cover may additionally or additionally include a laminated or substantially separate film layer that may be elastic to provide further enhanced liquid penetration resistance and / or elastic properties. Good. Elastic properties can also be added or reinforced by adding other materials to the outer cover as layers, bands or strips including elastic strands, bands, scrims, foams and the like. The film layer can be laminated with a washable or wash-resistant material. Film layers are KRATON (product of Kraton Polymers US, LLC, Houston, Texas), VISTAMAXX (available from ExxonMobil Chemical Company, Houston, Texas) Film Products Corporation) and elastomers based on a variety of latex-free elastic sheets available from Fullflex Elastomerics Worldwide, Greenville, Tennessee.

  Inclusion of an elastomeric material as a fibrous component of a fabric or nonwoven layer or as a film layer can be useful to adapt to the wearer's anatomy and movement around the wearer's buttocks and / or waist area, etc. Provides improved stretch and elasticity, as well as improved fit and comfort. In addition, if it is possible to include a film layer, additional liquid capacity can be imparted to the outer cover. The film layer is substantially liquid impermeable, but can include a vapor permeable film, providing breathability while wearing the outer cover, lowering the humidity in the outer cover, and where liquid containment capacity is desired The possibility of over-hydration of the skin can be reduced.

  The outer cover layers or elements are joined together by any means known in the diaper or garment art, including, for example, adhesives, mechanical bonds, ultrasonic bonds, stitching, sewing, over stitching, edging, etc. be able to.

  It is contemplated that any wash-resistant outer cover disclosed herein can be used with any embodiment of the wearable absorbent article disclosed herein. This exemplary wash-resistant outer cover can also be added for use in pant-type wearable absorbent articles.

  The reusable outer cover may need to be washed before reuse if it becomes contaminated with excreta such as urine, feces, or sweat, or environmental contaminants. The caregiver may also wish to wash and clean the outer cover, remove odors, add a pleasant fragrance, or generally restore its shape, neat feel, and / or appearance. In general, caregivers can expect that the more expensive the outer cover, the more likely it will be washable over many wash cycles without significant deterioration in the physical properties or appearance of the outer cover. A wash-resistant outer cover can generally be constructed of a less expensive material than a washable outer cover and therefore degrades more rapidly as the number of wash cycles is increased compared to a washable outer cover. For example, it may be expected to deteriorate so that it can no longer be used after fewer wash cycles.

  The aesthetic appearance of the outer cover after multiple wash cycles is important to the value of the outer cover perceived by some caregivers, but the acceptable appearance is highly dependent on personal preference. It is also acceptable to wear an outer cover with a more “worn” appearance at certain locations (eg home) or usage situations (eg at night or when the child has a disease such as diarrhea) Can be. Therefore, more importantly, in the case of wash-resistant outer covers, after at least one wash cycle, and in the case of washable outer covers after 10 wash cycles, their intended use Have the ability to respond to

  Because the wearer's excrement or load due to movement tends to move down the wearable absorbent article that is being worn, embodiments of the present disclosure may be drooping and / or wearing wearable absorbent articles. Or it can help prevent slippage. The wearable absorbent article can include a fixation system. In various embodiments, the fixation system is configured to collect at least a portion of the load acting on the article and / or distribute them to a place on the wearer's body where the load can be supported. be able to. The fixation system may be configured to secure itself to the wearer's body. In this way, the fixation system can balance at least a portion of the collected load due to the holding force provided by the fixation system. By balancing the collected load with the resulting retention force, the fixation system can at least assist in holding the wearable absorbent article in place on the wearer.

  The fixation system can be configured to collect the load acting on the wearable absorbent article, and can fix itself to the wearer's body and balance the collected load by the retention force resulting from the fixation . Throughout this disclosure, the term “fixed” refers to the construction of a part or some part or whole of the fastening system of the wearable absorbent article and part or some part or whole of the wearer's body. Refers to a relationship. If the fastening system is secured to a part of the wearer's body, at least a portion of the securing element is in direct and / or indirect contact with the body part while the article is worn by the wearer; The fixation system is configured to at least reduce and / or prevent relative movement between the fixation element and the portion.

  The fixation system can be secured to the wearer's body by one or more fixation elements of the fixation system configured to contact one or more of various portions of the wearer's body. For example, the fixation system can be at least partially fixed by wrapping one or more fixation elements at least partway around the front, back, and / or sides of the wearer's body, thereby Provides friction and / or reaction forces.

  In some embodiments, a body part having a relatively small radius of curvature can provide greater frictional thrust, which can tend to cause the anchoring element to wrap more tightly around such part. Because. This is due to the physical properties of a flexible material that is wound around a curved surface and placed under tension. In such a case, because the tensile force places the flexible material under tension, the flexible material is perpendicular to the curved surface and produces a normal force inwardly on the curved surface. According to the basic Capstan formula, the normal force is proportional to the tensile force divided by the radius of the curved surface. Therefore, at a predetermined tensile force, the vertical force increases as the radius decreases.

  Also by way of example, the fixation system may be at least partially fixed by fixing one or more fixation elements around and / or on one or more protruding portions of the wearer's body. And thereby provide friction and / or reaction forces. In some embodiments, the fixation element may have a tendency to more securely hang and / or ride on a body part that has a relatively large horizontal protruding portion (ie, can support a load). Since the reaction force from a normal body has an upward component, a relatively large horizontal protruding portion can provide a greater reaction force.

  In order to collect the load, secure itself to the wearer's body, and balance various forces, the fixation system can be configured to include one or more fixation elements. In some embodiments, the fixation element may be an elongate fixation element configured to hold tension. The anchoring element can follow a variety of paths on surfaces within the wearable absorbent article and / or on the outer surface of the wearer's body of the wearable absorbent article that includes the anchoring system. The shape of these surfaces can affect the shape of the path. The shape of the path can in turn affect the configuration of the fixed element.

  In a fixation system for a wearable absorbent article, the one or more fixation elements may be configured to at least assist in securing the fixation system to the body. Some anchoring elements can receive loads collected from one or more elements such as a chassis, fastener, leg cuff, or another anchoring element of the wearable absorbent article. Some anchoring elements can transmit loads and / or forces in the anchoring system. Some anchoring elements can provide a holding force through contact with the wearer's body. As a result, by balancing the load and force, the fixation system can at least assist in holding a wearable absorbent article that is stationary on the wearer.

  The securing element can be configured in various forms. The fixation element can be made from any material suitable to carry the tension of the fixation system. Part or some of the anchoring element or substantially all or all of the various elastic, inelastic, stretchable, non-stretchable, stretchable, and / or non-stretchable One or more of the material (s) and / or any other suitable material (s) and / or any combination of these materials may be included. The path of the anchoring element may be an integral continuous path or may be formed from a number of separate elements and / or separate areas arranged along the path. Some or some or substantially all or all of the anchoring elements can be straight, curved, square, split, or other shapes, or any combination of these shapes. In some embodiments, the fixation element can include a number of elements such as fasteners. One or several parts or substantially all or all of the anchoring elements are structured on one or more other elements (outer cover and / or waist cover and / or absorbent core) of the wearable absorbent article Associating and / or joining and / or attaching and / or durable attaching and / or refastenable attaching and / or embedding and / or integrating it can. When the fixation member is embedded in or integral with one or more other elements, the fixation member forms a distinctly different recognizable path within the structure. For example, when the securing member is integral with the outer cover, the path formed by the securing member can have a higher modulus of elasticity than the area of the outer cover around that path. As used herein, the term “joined” refers to a configuration in which an element is secured directly to another element, and the element is connected to one or more intermediate members, which intermediate member is connected to another element. A configuration in which an element is indirectly fixed to another element by being connected.

  The fixation element can be any suitable width or thickness. For example, the anchoring element can be 5 mm to about 100 mm wide, or any width within this range. The width and / or thickness of the anchoring element may be substantially uniform or completely uniform over one or more portions of the anchoring element or over the entire length of the anchoring element, and may vary over the length of the anchoring element. Good. In some embodiments, the fixation element can have a substantially uniform width of about 10 mm, about 20 mm, about 30 mm, about 40 mm, or about 50 mm. Throughout this disclosure, unless otherwise specified, the width of the anchoring element is the largest overall dimension across the path from one side edge of the path in the direction perpendicular to the centerline of the anchoring element to the other side edge of the path. As measured at a particular point on the path of the fixed element.

  One type of fixation element is a fixation band. The fixation band includes one or more physical elements, tension retaining elements, and / or areas disposed along a defined fixation band path of the wearable absorbent article. The fixation band can have sufficient force to transmit the resistance of tension from one end to the other and hold such tension in the fixation system. In some embodiments, a portion of the absorbent core of the wearable absorbent article has an implied anchoring band that is structurally configured to hold increased tension over that portion. Can be formed. In various embodiments, the fixation band can at least partially surround the lower torso of the wearer's body, eg, the back of the article.

  Another type of fixed element is a load distribution element (LDE). An LDE is one type of fixation band that induces and / or distributes the load of a fixation system for wearable absorbent articles. The LDE can accept at least some collected load by being bonded to one or more other elements of a wearable absorbent article, such as an absorbent core. The LDE can induce and / or distribute such loads by being joined to one or more fixation elements of a fixation system, such as a CAM or a fixation band. In various embodiments, the LDE can be configured to derive and / or distribute part or some of the load or substantially all or all from the absorbent core of the wearable absorbent article.

  Yet another type of fastening element is a spine. A spine is one type of fixation band that helps support the absorbent core of a fixation system for wearable absorbent articles. The spine includes one or more physical elements, tension retaining elements, and / or areas disposed along a defined spine path of the wearable absorbent article. The spine is oriented substantially transversely or completely transversely, or substantially longitudinally or completely longitudinally. A substantial portion of the spine path passes through a region of the absorbent core of the wearable absorbent article. In some embodiments, substantially all or all of the spine is contained within an area of the absorbent core.

  Yet another type of fastening element is a peripheral fastening member (CAM). A peripheral fixation member (CAM) is a fixation element that includes one or more physical elements, tension-holding elements, and / or areas disposed along a defined CAM path of a wearable absorbent article. The CAM pathway generally follows a curved surface in the wearable absorbent article or on the wearer's body. The CAM path at least partially surrounds the lower torso of the wearer's body. In some embodiments, the CAM path can substantially or completely surround the lower torso of the wearer's body. When the article is worn by the wearer, the CAM can follow a curved path, but the CAM has a substantially straight or completely straight appearance in an absorbent article laid flat. be able to.
